Which act focuses on the sale or rental of single-family and multi-family properties?

The Fair Housing Act is the correct answer because it specifically addresses discrimination in the sale or rental of residential properties, including both single-family homes and multi-family units. Enacted in 1968, the Fair Housing Act prohibits discrimination based on race, color, national origin, religion, sex, familial status, and disability. It was designed to create equal housing opportunities for all individuals, ensuring that everyone has the right to rent or purchase housing without facing discrimination.

This Act plays a crucial role in promoting fair housing practices and combating systemic inequities in housing access. Unlike the other laws mentioned, which may address broader civil rights issues or specific areas of discrimination, the Fair Housing Act is focused exclusively on the housing sector, making it the most relevant choice in this context.
